OK I know the listing is valid as I checked with NATS myself so I dont cast doubt on it but it is a strange one to me, so my question is why is 283.425 now an official radar frequency for Doncaster airport? Is this some kind of military arrangement?

It's quite possible 283.425 is a valid UHF frequency to provide a low level radar service to military traffic in the area although I would have thought rarely used but maybe someone living near to Doncaster could enlighten us.

Doncaster has civil approach and military approach frequencies, although the mil one is not always used. It is very much like most places across the uk, There is no LARS for doncaster once passed going south Military will call waddington lars if need be or london mil.If heading northbound, they will call RAF Leeming Lars or Director then the same with london mil or use scottish mil. Someone told me this a few months back

It is still listed on the NATS aerodrome specific pages as Doncaster Radar along with 126.225 which is listed both as Doncaster Approach and Doncaster Radar on the same document

These are possibilities:The ICAO international air to air freq 123.45 (which would solve any issues of the frequency potentially being in use anywhere in the world)UK government freq of 132.65 (used by coastguard, SAR, royal flights, Northolt)
